这个函数是从文件  职工信息.txt  中统计信息，总人数，大学生，高中生，初中生，其他。
文件都是对了的，刚运行到这个函数就出现：


int record(void)
{
    FILE *fp;
    int total=0, daxue_num=0, gaozhong_num=0, chuzhong_num=0, other_num=0;
    struct worker *p=NULL;
    char choice;

    printf("确实要统计数据(Y/N):\n");
    scanf("%c", &choice);

    if(choice=='Y')
    {
        if((fp=fopen("职工信息.txt", "rb"))==NULL)
        {
            printf("对不起，不能读入该文件\n");
            return 0;
        }

        p=APPLY;

        while(!feof(fp))
        {
            fread(p, sizeof(struct worker), 1, fp);
            total++;
            if(strcpy("daxue", p->degree)==0)
            {
                daxue_num++;
            }
            else if(strcpy("gaozhong", p->degree)==0)
            {
                gaozhong_num++;
            }
            else if(strcpy("chuzhong", p->degree)==0)
            {
                chuzhong_num++;
            }
            else
            {
                other_num++;
            }
        }
        free(p);
    }
    else
    {
        return 0;
    }

    printf("经统计:\n");
    printf("大学生\t高中生\t初中生\t其他\t总人数\n");
    printf("%d\t%d\t%d\t%d\t%d\t\n", daxue_num, gaozhong_num, chuzhong_num, other_num, total);
    return 0;
}
